With reference to FIG. 2, a bolt locking structure for a waterproof LED lamp according to a preferred embodiment of the present invention comprises: a first casing 10 and a second casing 20, wherein each of the first casing 10 and the second casing 20 is in a rectangle shape.
The first casing 10 includes multiple first protrusions 11 and multiple first recesses 12 which are arranged on each of four peripheral walls thereof respectively, wherein any two adjacent of the multiple first protrusions 11 are separated by each of the multiple first recesses 12, and any two adjacent of the multiple first recesses 12 are separated by each of the multiple first protrusions 11. The second casing 20 includes multiple second protrusions 21 and multiple second recesses 22 which are arranged on each of four peripheral walls thereof respectively, wherein any two adjacent of the multiple second protrusions 21 are separated by each of the multiple second recesses 22, and any two adjacent of the multiple second recesses 22 are separated by each of the multiple second protrusions 21. The multiple first protrusions 11 of the first casing 10 retain with the multiple second recesses 22 of the second casing 20, and the multiple first recesses 12 of the first casing 10 retain with the multiple second protrusions 21 of the second casing 20.
Multiple through holes 30 are coaxial and form on each peripheral wall of each of the first casing 10 and the second casing 20 respectively, wherein each of the multiple through holes 30 passes through each of the multiple first protrusions 11 and the multiple second protrusions 21, such that each of multiple connection bolts 40 inserts into the multiple through holes 30, thus locking the first casing 10 and the second casing 20 together. In this embodiment, four connection bolts 40 correspond to the four peripheral walls of each of the first casing 10 and the second casing 20, respectively.
When the multiple first protrusions 11 of the first casing 10 retain with the multiple second recesses 22 of the second casing 20, and the multiple first recesses 12 of the first casing 10 retain with the multiple second protrusions 21 of the second casing 20, said each connection bolt 40 inserts through the multiple through holes 30, thus locking the first casing 10 and the second casing 20 together.
A width of said each first protrusion 11 is less than that of said each first recess 12, wherein each of four L-shaped projections is defined on each of four corners of the first casing 10.
A width of said each second recess 22 is less than that of said each second protrusion 21, wherein each of four L-shaped trenches is defined on each of four corners of the second casing 20.
When the first casing 10 and the second casing 20 retain together, the multiple through holes 30 on said each peripheral wall of the first casing 10 are coaxial with those on said each peripheral wall of the second casing 20.
Said each L-shaped projection of the first casing 10 has an L-shaped orifice defined on a corner thereof.
Two ends of each of the multiple through holes 30 and the L-shaped orifice are machined at 45 degree chamfer.
Among the multiple through holes 30 and said each connection bolt 40 is arranged a silicone rubber.
A diameter of said each connection bolt 40 is 2.5 mm, and an error between said each connection bolt 40 and said each through hole 30 is 0.1 mm.
In assembly, the multiple first protrusions 11 of the first casing 10 are retained with the multiple second recesses 22 of the second casing 20, and the multiple first recesses 12 of the first casing 10 are retained with the multiple second protrusions 21 of the second casing 20, such that the multiple through holes 30 are coaxial. Thereafter, liquid silicone rubber is applied on said each connection bolt 40, and said each connection bolt 40 is inserted through the multiple through holes 30. After the liquid silicone rubber solidifies, said each connection bolt 40 is adhered in the multiple through holes 30. In addition, another liquid silicone rubber is applied on two ends of said each connection bolt 40, and the first casing 10 and the second casing 20 are fixed, after said another liquid silicone rubber solidifies.
Preferably, each of a first connection surface of the first casing 10 and a second connection surface of the second casing 20 has a silicone rubber film injection molded thereon, wherein the first connection surface of the first casing 10 faces the second connection surface of the second casing 20, a thickness of the silicone rubber film is 0.2 mm, and the silicone rubber film matingly contacts with the each of the first connection surface of the first casing 10 and the second connection surface of the second casing 20. Preferably, the silicone rubber film contacts with said each first protrusion 11, said each first recess 12, said each second protrusion 21, and said each second recess 22.
Thereby, when the first casing and the second casing retain together, said each first protrusion retains with said each second recess and said each first recess retains with said each second protrusion by using the silicone rubber film, and said each connection bolt locks the first casing and the second casing securely.
Preferably, the two ends of said each connection bolt are machined at 45 degree chamfer so as to avoid damage, after the first casing and the second casing are locked, hence the bolt locking structure is simplified and is not broken easily.
While the preferred embodiments of the invention have been set forth for the purpose of disclosure, modifications of the disclosed embodiments of the invention as well as other embodiments thereof may occur to those skilled in the art. Accordingly, the appended claims are intended to cover all embodiments which do not depart from the spirit and scope of the invention.
